The Verdict
The Canon EOS R100 is everything you need to start photography and nothing you don't. It uses Canon's proven 24.1MP sensor and delivers those beautiful Canon colors in every shot. No frills, no complexity - just solid fundamentals at the lowest price.
It makes sacrifices to hit this price point: no viewfinder, limited video specs, and no touchscreen. But if you're upgrading from a phone and want a real camera without breaking the bank, the R100 delivers.

In-Depth Performance
Image Quality & Sensor Performance
The 24.1MP sensor delivers solid image quality with Canon's excellent color science. JPEGs look pleasing with accurate skin tones and well-saturated colors. For daytime and well-lit scenes, the R100 produces images that rival more expensive cameras.
Autofocus System
Dual Pixel CMOS AF provides reliable focusing with 143 zones covering most of the frame. Face and Eye detection work well in good light, making portrait photography straightforward. The system is generation behind newer Canon cameras but capable for beginners.
Tracking moving subjects is where limitations show. Continuous AF at 3.5 fps is slow compared to the R50's 15 fps. For static subjects and casual shooting, it's perfectly adequate.
Video Capabilities
Video is the R100's weakest area. 4K is limited to 24fps with a 1.6x crop, making wide-angle shots difficult. 1080p60 is available for smoother motion. There's no log profile or advanced video features - what you see on screen is what you get.
For casual video clips and social media, it's acceptable. For serious video work or vlogging, spend more on the R50 or look at Sony's ZV-E10, which excels at video.
Ergonomics & Build
The R100 is extremely light at 356g. It feels almost too light - like a toy camera - but build quality is adequate for careful use. The grip is minimal, so larger hands may find it cramped.
The fixed, non-touch screen is the most noticeable cost-cutting measure. You can't flip it for selfies or tilt it for low angles. Menu navigation is button-only. If these limitations matter to you, step up to the R50.
Ideal Lenses for the Canon EOS R100
Canon RF-S 18-45mm f/4.5-6.3 IS STM (Kit Lens)
Buy the kit version. The lens is compact, stabilized, and covers useful focal lengths. Perfect match for the R100's portability focus.
Canon EF 50mm f/1.8 STM + Adapter
The classic "nifty fifty" with EF-RF adapter gives you f/1.8 for beautiful portraits. Cheap and cheerful, it transforms your photography.
Canon RF-S 55-210mm f/5-7.1 IS STM
Affordable telephoto for wildlife and sports basics. Stabilization helps compensate for the slower aperture. Good value for the reach.
The numbers, and where they come from
Published by the maker
| Sensor size (maker's figure) | 22.3 x 14.9 mm |
|---|---|
| Effective pixels | 24.1 MP |
| Pixel dimensions (3:2) | 6,000 x 4,000 |
| Native ISO range | ISO 100–12,800 |
| Continuous shooting | 6.5 fps (electronic first-curtain shutter) |
| Buffer (RAW) | 6 frames (RAW at 6.5 fps) |
| Battery (CIPA) | 430 shots |
| Weight with battery and card | 356 g |
| Viewfinder resolution | 2.36 million dots |
Maker figures checked on 25 Sept 2026 — maker's spec sheet. Continuous shooting, in the maker's words: One shot AF: Max. Approx. 6.5 shots/sec with Electronic 1st-curtain shutter, speed maintained for 97 JPEG(All sizes) or 6 RAW
Computed from those figures
| Pixel pitch | 3.72 µm |
|---|---|
| Sensor area | 332 mm² |
| Format factor | 1.61x |
| Light gathered vs 35mm | −1.4 stops |
| Print at 300 dpi | 51 cm |
| Diffraction limit | f/5.5 |
Computed from the figures above. Pixel pitch = sensor width / pixel count across. Light gathered = log2 of the area ratio to 36 x 24 mm. Diffraction limit = the aperture at which the Airy disc diameter (2.44 x lambda x N, lambda = 550 nm) reaches two pixel pitches. Other calculators use other thresholds and so quote other numbers.
